Week8 - Electronics Production

Missions of my week8 assignments:​

What should I achieve in this week:​

Group Assignment​

  • Characterize the design rules for your in-house PCB production process
  • Submit a PCB design to a board house

Individual Assignment​

  • Make and test a microcontroller development board that you designed
  • Extra credit: make it with another process

Electronic Production Notes​

PCB Fabrication Methods​

  1. Dead Bug Method
  2. Etching
  3. Machining
  • This is the method used for the assignment.

Machining Details:​

Machines​

  • Variety of machines used in different labs.

Tools​

  • 1/64 milling
  • 1/32 milling
  • V-bits
  • Tapered bits, etc.

Fixturing​

  • Used for holding the board in place without movement.

Underlay​

  • Prevents drilling down to the machine bed.

Zeroing (Important)​

Ensures the starting point of the mill with three methods:

  • Mounting
  • Lowering
  • Probing (using a tool)

Set-Screws, Collets​

  • Choose the right mill for cutting (available in the labs).

Lifetime​

  • Refers to the tool's lifespan - usage must be monitored.

Deburring​

  • Process of removing impurities from the board.

Cleaning​

  • Cleaning the board after processing.

Machine Cutting​

  1. Use PNG or SVG for lossless resolution in machine cutting.
  2. Convert PNG or SVG images with mods, selecting the appropriate mill, like a V-bit or other sizes such as 1/64 or 1/32.
  3. Set related parameters to view the final outcome and machine cutting trace.
